GRAIN-SEPARATOR.

v SPECIFICATION' forming part of Letters Patent No. 305,528, dated September 23, 1884.

Application filed May 9, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, ANDREW B. MONOK, of Fargo, in the county of Cass and Territory of Dakota, have invented a newv and Improved Grain-Separator to Remove Gockle, Small Seed, Vild Buckwheat, and like Impurities from Wheat and other Cereals; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part Of this specification, in Which- Figure l is an isometrical perspective View of the separator open to show the interior construction. Fig. 2 is a vertical cross-sectional view showing the grain passing down view of a section of one of' the zigzag screens.

My invention relates to grain-separators; and it has for its object to successfully remove cockle, cheat, and like impurities from Wheat and other cereals by gravity-screening, whereby I obtain a thorough and complete separation in a most economical manner.

My invention consistsin sundry details of construction of mechanism, as is hereinafter fully described, and specifically pointed out in the claims.

In order that those skilled in the art may make and use my invention, I- will proceed to describe the manner in which I have carried it out.

In the said drawings, A is the casing of the separator, one side of which is hinged at b b, so as to give ready access to the interior of the machine. Vithin the casing isa zigzag partition, B, made of alternate strips' of im` perforate material, d, and strips of perforated material, e, set at an angle to each other, as shown. Secured to the hinged side of the casing is a partition, C, similarly constructed with partition B, 'with the exception that the `perforated portions e alternate with the per` forated portions c, and each perforated portion e lies opposite to and parallel with an imperforate portion, d, of partition B,fso that the protruding angles of partition C enter the included angles of partition B, a space or zigdiminished at will.

Fig. 3 is an enlargedY zig passage, f, being left between the partitions forthe passage of the grain. Thepartition C is secured to the frame by means of rods g, which pass through it near the top and bottoni, and the ends of which protrude through slots g in the casing, and are provided with screw-threads and nuts h. rlhe slots and nuts provide for an adjustment of one screen to and from the other, so that the size of lthe grain-passage may be increased or rllhe top of the casing is provided with a feed-hopper, il), having an adjustable'slide, i, secured by slots and bolts,

whereby the size of the feed-opening t" can be made of-a proper size to correspond with the size of the grainpassage. The bottom section of partition C is imperforate, but is provided witha series of passageways, k k, registering with like passage-ways, 7a Zs, in the lower perforated section of partition B, to conduct the cockle and other refuse to a proper discharge-opening, Z, on one side of the machine or casing, while the cleaned grain passes,r out at the opening m in the opposite side of the casing. (See Fig. 2;)

Preferably, I make the perforated sections of lthe partitions with a narrow strip of sheet metal, n, at their tops, to receive the-impact of the falling grain and avoid detrimental wear on the wire-gauze.

Secured to one side of the hopper is a ring, hook, or other fastening device, o, to engage with a fastening device, p, on the end of a prop, P, provided to aid iii-sustaining the cleaner ina perpendicular position, so that the base need not be broadened. rlhus space is economized. i

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1 The main casing A, provided with the zigzag screeningpartition B, in combination with the hinged portion of the casing provided with the zigzag screening-partition C, substantially as specified.

2. The zigzag screening-partition B, in` combination with the zigzag screening-partit-ion C and adjustable securing devices, whereby the partitions eah be adjusted to and from with each other when the hinged portion is each other7 as set forth. closed, all constructed substantially as set l 3. The zigzag screening-partitions B C, in forth. combination with the passage-Ways k, at- ANDREW B. MONGK. 5 tached to one screening-partition, and pas- Witnesses:

It is hereby Certified that in Letters Patent No. 305,528, granted September 23,1884, npon the applieation of Andrew B. Mouok, of Fargo, Dakota Territory, for an iniprovement in Grain Separatore, the name of the patentee was incorrectly Written 1` and printed Andrew Monekfinstead of Andrew B. Mouck; and that the proper correction has been made in the files and records pertaining to the ease in the Patent Office, and should be read inthe Letters Patent to rnake it conform thereto.
